- 1 Scope
- NOTE This standard does not deal with: [Go to Page]
- 2 Normative reference
- 3 Definitions [Go to Page]
- 3.1 range hood
- 3.2 recirculating-air range hood
- 3.3 air-extraction range hood
- 3.4 rated voltage
- 3.5 grease absorption factor
- !NOTE To the grease filter belong all detachable coverings, filter frames, supports or the like, which are located in the air stream and are intended to be removed for cleaning. " [Go to Page]
- 3.6 odour reduction factor
- 3.7 odour dispersion time
- 3.8 external blower
- 4 Classification
- NOTE A range hood may be constructed to incorporate both types. [Go to Page]
- 5 List of measurements
- 6 General conditions for measurements [Go to Page]
- 6.1 Test room
- 6.2 Installation
- 6.3 Supply voltage
- 6.4 Filters
- 6.5 Fan control
- NOTE 1 If a boost position is incorporated, this is not taken into account.
- NOTE 2 A boost position is a setting of a control for occasional use which results in a higher temporary fan speed. [Go to Page]
- 7 Overall dimensions
- 8 Maximum effective capture area
- 9 Length of the supply cord
- 10 Mass of the range hood
- 11 Volumetric airflow
- NOTE 1 A pressure/air flow curve is determined for the range hood under test.
- NOTE 2 Alternative working points corresponding to other pressure drops may be specified instead, in which case the pressure drop has to be stated in the report. [Go to Page]
- 12 Grease absorption
- For range hoods with an external blower the external blower does not need to be mounted during the grease absorption test. The desired airflow rate can instead be achieved by using the auxiliary fan and controlling the air flow with a suitable device."
- NOTE 1 In case of doubt, the absolute filter is dried for a further 3 h during which time the mass should not reduce by more than 0,5 g.
- !Note deleted".
- !NOTE 2" The drip-rate is approximately 45 per minute for oil and 80 per minute for water.
- !NOTE 3" Oil which drips from the filters during the drying process is added to the mass determined. [Go to Page]
- 13 Odour extraction
- !Note deleted".
- NOTE 1 When handling MEK, normal precautions have to be taken.
- NOTE 2 When testing air-extraction range hoods, measures should be taken to prevent the inlet-air from being contaminated with MEK from the outlet-air. "
- NOTE 4 The concentration in the test room (C1) can be measured without any range hood being installed."
- !NOTE 5" The room is considered to be adequately sealed if the concentration of MEK in the room drops by less than 5 % 1 h after the solution has been distributed.
- !NOTE 6" Flame ionization equipment is suitable for measuring the concentration of MEK.
- !NOTE 7" Recirculating-air range hoods are not switched off before measuring C2.
- !NOTE 8" The odour dispersion time is not measured for air-extraction range hoods. [Go to Page]
